LOAD CHAIN
Clean and Inspection
First clean the load chain with a non-acid or non-caustic
type solvent. Then slack the chain and make a link-by-link
inspection for nicks, gouges, twisted links and excessive
wear or stretching. Chain should be gaged throughout its
entire length and replaced if worn beyond serviceable limits.
Gaging Load Chain Wear
To determine if load chain should be continued in service,
check gage lengths as indicated in Figure 15. Chain worn
beyond length indicated, nicked, gouged or twisted should
be replaced before returning hoist to service. Chain should
be clean, free of twists and pulled taut before measuring.
To aid in gaging load chain wear. A chain gage can be
obtained from CM. This can be obtained by ordering chain
gage Part No. 3191.
Note that worn chain can be an indication of worn hoist
components. For this reason, the hoist’s chain guides, hook
blocks and liftwheel should be examined for wear and
replaced as necessary when replacing worn chain.
Also, these chains are specially heat treated and hardened
and should never be repaired.
Figure 15. Gaging Load Chain Wear
IMPORTANT: Do not use replaced chain
for other purposes such as lifting or
pulling. Load chain may break suddenly
without visual deformation. For this rea-
son, cut worn chain into short lengths to
prevent use after disposal.
PROTECTOR
The Protector should operate for the normal life of the hoist
without service. The device has been lubricated and cali-
brated at the factory for a specific model of Lodestar Hoist
and is not to adjustable or interchangeable with other mod-
els. For proper overload protection, be sure before installing
a Protector that it is correct for the unit. The edge of the
spring washer of the Protector has been color coded at the
factory as follows:

WARNING
Using other than CM supplied load chain may cause the chain
to jam in the hoist and/or allow the chain to break and the load
to drop.
TO AVOID INJURY:
Due to size requirements and physical properties, use only CM
HoistAloy load chain in the Lodestar Hoists.
